Embedded systems, sensors & rapid hardware bring-up
Hands-on embedded and hardware R&D — from early prototypes to working systems for startups and R&D teams.
What I do
Embedded firmware
STM32-based embedded firmware for real-time systems: low-level drivers, peripherals bring-up, ADC/DMA, timing-critical code, basic DSP and signal processing. Practical debugging with oscilloscopes and logic analysers, focusing on reliable, maintainable firmware rather than demos.
Sensors & electronics
Sensor integration and electronics development: analogue front-ends, TIAs, signal conditioning, filtering, and data acquisition. Working with optical, inertial, pressure and other sensors, bridging analogue signals to digital processing with a solid understanding of noise, bandwidth and limits.
Prototyping & testing
Rapid hardware prototyping from schematic to assembled PCB, including bring-up, early validation and hands-on testing. Basic mechatronics and enclosure work — practical housings, mounts and assemblies, with focus on fit, integration and real-world use rather than aesthetics.
How I Work
We start by clarifying the scope — goals, constraints, and what “done” actually means.
Early prototypes help turn assumptions into something tangible and testable.
Decisions are based on practical testing and real measurements, not guesswork.
Short feedback loops keep progress visible and allow adjustments before problems grow.
